Tiivistelmä

Since the available digital information grows rapidly, the utilization of the information visualization becomes of utmost importance to perform complex data analysis tasks. With the help of the visualizations, hidden facts about the data such as patterns, outliers and tendencies can be revealed. Strategic decisions can be established with the insights gained during the interactive data exploration.

The latest developments in browser technology have enabled developers to build interactive web-based visualizations to target broader audience. This thesis is dedicated to investigate usage of JavaScript in web applications. After describing the main theories and frameworks in the information visualization literature, a number of visualization tools are introduced. D3.js is selected as the visualization framework to visualize Tampere Unit for Computer-Human Interaction Research Center s publication data.

According to design considerations and experiment gained from visualization of the web-based publication data, it is possible to create powerful and reusable interactive visualizations with JavaScript frameworks. Theories and frameworks mentioned in the literature review worked as a guideline while visualizing the web-based data.
